But in explaining himself, Gates did not significantly alter his stance.

He said that with “the right safeguards,” it’s “valuable” for the government to have access to user data in cases where it’s acting on Americans’ behalf, “like stopping terrorist that could get worse in the future.”

The key is to strike the right balance between national security and personal privacy. “The extreme view that the government always gets everything—nobody supports that,” he said. Likewise, “Having the government be blind—people don’t support that,” he said. “I do believe there are sets of safeguards where the government shouldn’t have to be completely blind.”

Gates did not specify what those caveats should be.

In his earlier interview with the FT on Monday, Gates seemed to justify the FBI’s demand that Apple (aapl) weaken the security of the gunman’s iPhone because it was a specific request. “They are not asking for some general thing, they are asking for a particular case,” he told the paper. And he denied that the the FBI’s demand would set a wider precedent.

Gates didn’t necessarily backtrack from that view with Bloomberg on Tuesday. He said that technology can, at times, empower terrorist activity. “It’s not just that they can kill a few people; it’s through nuclear, biological [weapons that] they could kill a lot,” he said. “We do want the government out there trying to stop those things from happening.”

Gates said that courts will decide the current spat between Apple and the FBI, but he hinted that Congress should use the controversy as an opportunity to tackle the safety versus privacy issue.
